Using HSV Thresholding¶ HSV thresholding uses hue, saturation, and value to threshold images. Unlike RGB, HSV separates the image intensity, from the color information. This is very useful in computer applications such as vision tracking. In FRC, HSV is a great tool to detect the reflective vision tape if using a LEDs to illuminate the tape.

OpenCV’s RGB-to-HSV and HSV-to-RGB conversion only stores the Hue component as an 8-bit integer in the range 0 to 179, when it could have easily used 0 to 255. This means that if you use OpenCV’s cvCvtColor() function to obtain a HSV image, you will loose some of the color resolution, since it is basically storing the Hue as a 7-bit number ...

replace color, do you mean you want to change red to blue,blue to green or yellow red etc? If this is what you want, there are a very simple algorithm 1 : change your color space from RGB to HSV (or HSL etc, the important part is separate the color into hue, saturation and intensity)

RGB to HSV¶. This example illustrates how RGB to HSV (Hue, Saturation, Value) conversion 1 can be used to facilitate segmentation processes. Usually, objects in images have distinct colors (hues) and luminosities, so that these features can be used to separate different areas of the image.
